intake adapters
 

looking for a 12a to 13b 4 port intake adapter to use a 12a intake on a 13b anyone knows who sells one?

I don't believe anyone sells an adapter like this. Why do you want one?

If RB no longer has them, hit the for sale sections, ebay and Austraila.

Mazdacomp has adapters. Not sure if they have he one you need though. I think they have one that goes the other way. Maybe you can modify that to work.

Try some of the Aussie shops. You can get adpators to suit almost any manifold/engine configuration.

found the intake i needed so no need for an adapter

well if u still need it i believe tweakit.net sells them
